This is me being a little bit prickly, but I'd be disappointed if a few of them aren't there to do State of Play reactions. It's a Thursday at 3pm for them and my hope is they'd already be using the studio anyways. The last State of Play got them 40k views on youtube and a substantial audience that watched it live with them on Twitch.
Also, IF something major were to be shown, it would be a real missed opportunity not having that on tape. Just like how it was a bummer when they weren't around when Cadence of Hyrule was dropped unexpectedly in that Indie Direct. Even if the State of Play is awful, that's still entertaining to watch as well. No need for a 30-minute pre and post-show for this, but it would be a bummer if this community is watching it elsewhere.
To be clear, if an event is going to be something they categorically aren't interested in (for instance, Borderlands 3 reveal), no need to assemble for one of those. But if it's of a caliber of a Nintendo, Sony or Microsoft, I really hope they make every effort to be around. Especially because it seems Sony is being kind of coy regarding what's on the agenda for this one.
I think you'd have to make the Sonic 2 play, because Sonic 3 & Knuckles may not count. You could perhaps pitch Sonic Jam (Sega Saturn) but I'm not sure if that would be in the spirit of the Hall. Games that should get in there:
-Panzer Dragoon Saga
-Phantasy Star Online Episode I & II
-Shenmue 1 or 2
-Streets of Rage 2 (Huber attempted)
-Sonic 2
-OutRun
...
a few years pass
...
-Yakuza 0
Hah, I choose to look at this list from the bottom up. Yakuza 0 first, then a few years pass, then I'd be willing to go for some of those other games.
